Rol\n(University of Leicester) report on behalf of a larger collaboration:\n\n\"We reobserved the position of the GRB 061121 afterglow at 4.8 and\n8.6 GHz with the Australia Telescope Compact Array at November 27\n14.11 UT to 20.88 UT, i.e. 5.95 - 6.23 days after the burst (GCN 5823).\nWe do not detect a radio source at the position of the optical afterglow\n(GCN 5824). The three-sigma rms noise in het map around that position is\n126 microJy per beam at 4.8 GHz, and 129 microJy per beam at 8.6 GHz.\nThe formal flux measurement for a point source at the location of the\noptical afterglow is 7 +/- 42 microJy at 4.8 GHz, and -20 +/- 43 microJy\nat 8.6 GHz.\n\nWe would like to thank the staff of the Australia Telescope National\nFacility, in particular Philip Edwards, for obtaining these\nTarget of Opportunity observations.\"",
